宜調整しうる。 1 is the soil cultivator of the present invention. The structure is such that an appropriate number of front vertical brackets 3 are attached at predetermined intervals to a tool bar 2 supported on the tractor so as to be orthogonal to the traveling direction F of the tractor, and these brackets 3 are connected with pins P. A rear vertical bracket 6 is connected via the upper and lower arms 4 and 5, and the lower end of the rear vertical bracket 6 has a direction in which the tractor moves, and a frame 7 is fixed in a horizontal state. A ruler wheel 8 is provided at the tip of the frame 7 so that the support height can be freely adjusted.
A soil blade 9 is provided at the rear end so that the support height can be freely adjusted. An elastic rod-shaped shaping sub-device 10 is protruded from the upper left and right sides of 9. As shown in FIG. Therefore, although the tool bar 2 may be a single piece, it is composed of left and right bars 2B that are telescopically fitted from the left and right into a rectangular cylindrical central tool bar 2A located at the center.
It is configured to be fixed at a desired position with a set bolt 2C. The relationship between this tool bar 2 and the front vertical bracket 3 may be fixed by welding or by using U-shaped bolts, but in the case of this embodiment, the center part of the tool bar 2 is fixed. The two ends are welded together. As a result, when changing or moving the ridge width, the U-shaped bolt or set bolt 2C can be loosened and moved to set it in a predetermined position. Further, the rear vertical bracket 6 and the frame 7 are fastened and fixed with bolts 7A. The vertical frame 8A supporting the ruler wheel 8 is mounted so that it can move up and down within a receiving hole formed at the tip of the frame 7, and can be adjusted to a desired height by tightening a set bolt 8B. Furthermore, the support of the soil blade 9 is as follows. That is, the support rod 9C that supports the soil blade 9
is inserted into a receiving hole provided at the rear of the frame 7, and can be adjusted to a predetermined height by tightening and loosening the set bolt 9D. The shaping sub-device 10 includes a rod-shaped body 10A having a high-pressure hose with a piano wire inserted in its axis, and a bracket 10B having a vertically elongated hole 10B' fixed to the inner end of the rod-shaped body 10A.
0B is a long hole 9 attached to the back side of the blade 9A.
It is fixed to a receiving metal fitting 9C having a diameter C' with a bolt 9D. Therefore, by loosening this bolt 9D, it is possible to move it inward and outward along the elongated hole and adjust the support angle with respect to the ground as appropriate. A subsoiler blade 11 is attached to the lower end of the support rod 11A inserted into the receiving hole of the frame 7. Reference numeral 11B denotes a set bolt for fixing the support rod 11A to the frame 7, and in this case as well, the support height can be adjusted as appropriate by tightening and loosening the set bolt.

ついで、本案のものの作用を効果と共に説明す

影響を与えることになる。 In the field (field), vertical bracket 3, arm 4,
5. The vertical bracket 6 and other components work together when the ruler wheel touches down on the field, the vertical bracket 6 moves in conjunction with the frame 7 according to the unevenness of the field, and the arms 4 and 5 move in conjunction with each other. The soil blades and subsoiler blades set in predetermined positions adapt to changes in uneven surfaces and gaps in sloped fields (joints during burrowing work), etc., and crush subsoil and cultivate soil for crops 12 such as potatoes. You can perform tasks such as this in a consistent and accurate manner. Without a device that can perform such automatic height-lowering operations, it would not be possible to adapt to the above-mentioned field conditions, and in the case of potatoes in particular, the soil would not be leveled consistently, resulting in a lot of so-called green potatoes, which would have a major impact on crop growth. It turns out.

次に培土刃の作用について述べると下記の通り
である。 Next, the action of the soil blade is as follows.

ことになる。 The condition of the field before cultivating is as shown in FIG. 4, and the straw portion 12A of the crop 12 has not turned into a stem mass. In this case, since the soil cutting blade is approximately V-shaped from the front, the straw portion will not be cut.
Therefore, referring to FIG. 3, it is possible to mound the ridge high and wide using the soil blade, but the soil blade alone does not cover the root portion 12B of the crop with soil. In the case of the present application, since the shaping sub-device 10 is provided, the shaping soil can be reliably shaped at the root portion 12B. In this way, when it rains if the soil cannot reach the roots, water will accumulate in this area, making it difficult for water to penetrate, leading to a drop in temperature, and the stems of potatoes will rise upwards, causing green matter. Make it bigger. The present invention can prevent such inconvenience. In addition, since the above-mentioned auxiliary blades are shaped like hollow round rods, they do not damage the crops even if they come into contact with them, and they also allow soil clumps to escape backwards and downwards, allowing only fine soil to be collected in the ridges, resulting in good growth and quality. This will lead to an increase in yield.

り畦巾に充分な土を寄せることができる。 Furthermore, piano wire of an appropriate diameter is inserted into the hollow round rod-shaped rubber high-pressure hose to give it elasticity and resilience, so it is flexible against the resistance of the soil and has sufficient ridge width. You can collect soil.

である。 In addition, since the resin plate 9B is stretched over the surface of the blade body 9A, there is less soil adhesion and resistance, which improves the flow of soil and improves the performance of the auxiliary blades, which have round rod-like elasticity and can be adjusted by sliding. It can be used effectively.
